There has been a bit of discussion about this - some people feel that always reading the words with the accents is misleading because Russian people never write them like that, so learning them that way is pointless... as long as you have the audio to listen to. We are getting more audio all the time and should soon have a pretty comprehensive coverage.
The other plan is to put the Russian with no accents as the main "word" and then to have the version with accents in the "pronunciation" field. That way your wouldn't be tested from the accented version, but you would see it pop up after you answer the question. How does that sound?
and maybe, exercises with accent and without: as the "plants" grow, the accent can and has to "disappear" .
ps: my wife can record words/phrases (in Russian) but we would like theses recordings to stay free as we do them for free. (same license as the others recording at http://oldshtooka.yojik.eu/ : Creative Commons Attribution 3.0 Etats-Unis)
